Flow Injection on-line Preconcentration with Anion-exchange-resin and Flame Atomic Absorption Spectrometric Determination of Trace Cadmium(阴离子树脂微柱在线预富集火焰原子吸收法测定痕量镉)
建立了流动注射在线微柱预富集-火焰原子吸收(FAAS)法测定天然水中痕量镉的体系.在溶液pH7.2条件下，8-羟基喹啉-5-磺酸与Cd2+形成的络阴离子被填有阴离子树脂的微柱吸附而富集.用1mol/L硝酸溶液洗脱树脂上所吸附的镉.洗脱液在线输入FAAS测定.当采样速率为24次/时，富集倍数为10，检出限0.5μg/L，工作曲线线性范围0～100μg/L，RSD为1.0%(n=11,Cd2+浓度为100μg/L).本体系已用于天然水样中痕量镉测定，回收率90%～106%....
